You have to remember which directory you are in:

#untested
last_directory = None
for file in DirectoryWalker("."):
    directory = os.dirname(file)
    if directory != last_directory:
        color = random.choice(["red", "green", "blue"])
        last_directory = directory

    # do whatever you want with file and color
    print color, file
